Spectroscopy using sum- and difference-frequency generation in molecular solids.
Physical Review Letters 51 (24), pp. 2221-2223.
Both sum- and difference-frequency generation in org. materials were demonstrated and explored under conditions where all 3 waves (w1 and w2 ingoing and w1 +- w2 out-going) were resonant with mol. transitions. The expts. were carried out in centrosym. media in which a small elec. field was used to distinguish the polar sublattices. Unique elec. field dependences of the paramagnetic signals were discovered. The spectroscopic line narrowing and dephasing-induced coherent-emission resonances of these c(2) processes make them useful new spectroscopic methods.
